Aquascape Algaecide for Pond, Waterfall, and Water Features, 32-Ounce, 96024

Have been using this product for a couple years. Works well if used every 7-10 days in the summer months. Has never interfered with birds drinking from our pond. We do not have fish, but label indicates it is safe for fish as well.

Great Product

Taking a while to kill the algae in my pond, but the water is so crystal clear, I can now *see* the algae that remains without any trouble :)

I live in a hot humid climate. I have a small pond that is about 15 inches deep. No fish but lots of tadpoles that I don't want to harm. Pond was very green and gooey from the heat. My fountain pumps lots of water so I used this product per label instructions. Water started to clear up nicely. So I drained and cleaned the pond and added all new clear water. I've been using this product as directed on the bottle and the water has remained clean and clear. The cost is reasonable. I will definitely purchase this product again.

I’ve kept buying it every year for my fountain so it seems to work at keeping water clean and controlling algae. Lasts all year. Good quality.

If I could give negative stars I would. The video for this product shows a woman putting it into her Koi pond which gives the illusion it is safe for Koi. It also states in its advertising to be safe for fish and plants. This product almost killed my entire Koi pond. I spent 16 hours emptying my pond in a panic because all of my fish were gasping for air, I have a 5000 gallon Koi pond with plenty of aeration as well as a large waterfall . I spoke to numerous specialist, who all told me this product should be taken off the market as it is poison. It has misleading claims and misleading advertising. I can’t stress enough not to buy this product. In addition to killing 2 baby fish, it also killed plants in my pond. This product needs to be taken off the market!!! I cannot stress enough, not to buy this product.

I'll start with a disclaimer that the product does work in controlling algae in a pond where you have fish. With that said, you have to be EXTREMELY careful when measuring this out. You have to know how much water you have in your pond and use ONLY the recommended amount. If you are in a rush or if you guess, your fish will end up dead. This happed to me, and I acknowledge that it was my fault that I killed my ten year old fish when I was in a rush. I won't use it again; more of a safety precaution. I'll figure out other methods of controlling algae. So, I won't bash the product. It works. Just know that if you make a mistake that it will kill your fish.

We have a coi pond approximately 12 feet x 5 feet x 2.5 feet deep. Eight cascading waterfalls. String algae begins as soon as the weather warms. Using this product, along with regular maintenance, has eliminated the algae problem completely. Fish and frogs are thriving.
